FORD, ENGLAND.

APPERLEY BRIDGE, NEAR BRAD- .AFPARATUS FOR USE IN THE MANIIFACTURE OF' ARTIFICIAL SILK.

Application filed June 21, 1926, Serial No.

This invention relates to apparatus for use. in the manufacture of artificial silk from cuprammonia cellulose solutions according to the stretch spinning method, and more particularly to funnel fastening and suspending means, the chief object being to ensure a perfectly tight joint between the spinneret top and the ring and also between the ring and the cylinder or funnel, while at the same time providing for the easy removal of the spinneret top from the ring.

According to the invention, the spinneret top is adapted to be secured to the ring by means of a locking plate adapted to engage projections on the ring while packings are provided between the ring and the cylinder or funnel and between the spinneret top and the ring for ensuring tight joints between the parts.

In order that the invention may be clearly understood and readily carried into effect, the same will now be more fully described with reference to the accompanying drau ings; wherein Figures 1, 2 and 3 are respectively an elevation, plan and vertical section of a spinneret top, ring and cylinder or funnel.

Referring to the drawings, neret top provided with a supply regulating cock 2, and nozzle 3; 4 is the ring having the usual inlet and suction pipes 5, 6, and 7 is the cylinder or funnel. The ring 4 is provided with a rubber or other internal p acking 8, adapted to engage the upper portion of the cylinder or funnel 7, and a second rubber or other packing 9 is adapted to be expanded within a peripheral-groove or. recess 10, formed in the upper portion of the cylinder 01' funnel 7, by being compressed between the packing 8 and an annular compression member 11, adjustably mounted relatively to the ring 4 by means of screws '12 adjustablysecu-ring the two parts together. The spinneret top 1 is adapted to be secured to the ring 4 by means of a rotatably'mounted locking plate 13, having slotted members 14 adapted to engage outwardly projecting pins or lugs 15 on said ring 4 in the manner of a bayonet joint, while a rubber or other packing 16 is provided within an annular groove or recess 17 in the underside of the spinneret top 1 for engaging the upper portion of the ring 4 and ensurmg a tight joint 1 is the spin- 117,535, and in Great Britain July 2, 1925 between the two parts. The locking plate 13 is secured toand rotatably mounted on the spinneret top 1 through the medium of screws 18 passed through arcuate slots 19 formed in said locking plate 13, while the latter is provided with an extension or handie 20, for use in rotating the said plate 13 when securing the spinneret top 1 in position or removing it from the ring 4.

I claim 1. In an apparatus for the purpose described, the combination with a spinning vessel, of a suspending ring surrounding the upper end of said vessel, a spinneret top extending into said ring and over the upper edge thereof, a gasket interposed between said top and ring, and a locking plate adjustably supported on the top and provided with hook shaped members adapted to engage the ring to retain the top in position and clamp the gasket to provide a fluid tight joint between the ring and top.

2. In an apparatus for the purpose described, the combination of a spinning vessel having an'annula-r groove formed in its exterior surface adjacent its outer end, a sus pending ring surrounding the said outer end of the vessel and having a skirt extending across said vannular groove, a packing within the skirt of said ring in alignment with said annular groove, a compression member adjustably connected with the ring and adapted to cooperate with said packing to force the packing into said groove, and a spinneret top supported by the ring and extending within the same into the spinning vessel.

' 3. In an apparatus for the purpose described, the combination of a spinning vessel, a suspending ring surrounding the upper end of said vessel and having at its lower end an annular recess adjacent the vessel, a spinneret top supported by said ring and extending therethrough into the vessel, a gasket interposed between the ring and top, means for detachably connecting the top and ring and compressing said gasket, packing within the recess at the lower end of the ring, and means adjustably connected with the ring for compressing said packing.

1. In an apparatus for the purpose described, the combination of a spinning vessel, a suspending ring surrounding the upper 0nd of said vessel and providing a chamber communncating with the vessel and having suitable inlet and outlet openings, said ring being provided with a plurality of outward- 1y extending projections, a spinneret top supported by said rin and extending therethrough into the spinning vessel, a locking plate adjustably connected with the top and provided with means for engaging said projections on the ring to detachably connect 10 said top and ring, and means for maintaining a fluid tight joint between the ring and spinning vessel.
